【Sai Gado】Leaving the main house with Mana

It’s the first time in over a decade that Subaru Kanameishi (19), a prep school student in Tokyo, has been summoned by her family in the mountains to help preserve the Kanameishi bloodline. He is asked to have a baby with his cousin Mana (36), whom he thought was his aunt, in order to preserve the lineage of the Yameishi family. In order to pay for her father’s treatment, Subaru accepts the request, although she is confused.
